BII7690 Series NDT & Imaging Transducers: High Axial and Lateral Resolutions
BII-7690 series low Qm (Mechanical Quality Factor) broadband ultrasonic transducers (Longitudinal, Shear, and Guided Waves) are designed primarily for use in ultrasonic pulse system: short-distance echo sounding underwater, NDT (Non-destructive Testing), and acoustical imaging (Microscope, Holography, and Tomography). The typical Qm is from 1 to 3 which results in clean pulse responses. Concave (bowl or spherical sector) acoustic apertures are available to increase lateral resolution. Beam steering and focusing are implemented with linear (rectangular) array. They are immersion transducers and can also be used as contact transducers. The couplant (water, gel, grease, oils, commercial couplant, and shear-wave couplant) is a necessary material to provide efficient acoustic coupling between the transducer face and the subject (piece under test). Plastic and rubber housing resist attack by acids, alkalis, salt solutions and most other chemicals. There is no risk of corrosion when exposed to naturally corrosive conditions. They will not rust or corrode from electrochemical and galvanic environment. Solvents shall not be used with transducers, such as hydrochloric acid, isopropyl alcohol, ethyl lactate, acetone, xylene, Iso hexanes, mineral spirits, etc... the transducers MUST not be used with flammable and/or explosive materials.
